A 24-year-old Fontana man who had just left an area hospital was struck and killed by vehicles while walking along the freeway early Saturday, Oct. 24, Colton Police Department Watch Commander Steve Davis said.

Joseph Gallo was walking westbound on I-10, just west of Pepper Avenue in Colton, when he was struck, a San Bernardino County Coroner’s Office news release states.

Paramedics responded within minutes, but Gallo was unresponsive. He was pronounced dead at 12:54 a.m.

Gallo had left Arrowhead Regional Medical Center earlier that evening on his own, after receiving medical treatment, Davis said.

“We’re still investigating at this point, we’re not sure exactly what happened,” Davis said.
